Keithley 2300 Series Stability

Post by BrianJCongdon » January 12th, 2015, 9:20 am

I am looking for a supply with extremely high stability/low drift. I need to source up to 1A and will never exceed 24V (I could go as low as 5V.) What do you suggest?

I would suggest Model 2200-30-5.
This is a single channel power supply that can output up to 30V at 5A.
The specs are attached.

I searched the 2200 series document and couldn't find a Stability or Drift spec. The data sheet for the 2300 series lists Stability as 0.01% + 0.5mV over an 8 hour period. Ideally, I'm looking for a supply that is more stable than the 2300 series; anything 5V or above will work.

The Model 2300 series seems to be the only supplies that have stability and drift specs.
Even the SMUs(source measure units) do not have these specs.

Can you provide me with the Ripple and Noise specs for the 2300 series? The Specifications section of the downloadable instruction manual (Appendix A) is blank.

I'm specifically looking for the noise and ripple specs for DC Voltage output (Battery.) The only reference I can find to noise in the documentation is in the Pulse Current Measurement Operation section.

The 2300 Series make use of a switching power supply to generate their output voltages and make use of an integrating A/D converter for the measurements.

I suggest you again consider one of the linear power supply products such as the 2200-32-3.
I've uploaded an application note on understanding the Linear Power Supply Specs including concepts of Stability from the provided temperature coefficient, load and line regulation and calibration interval information.
